Call For Papers

Wireless sensor networks (WSNs) have witnessed a tremendous upsurge in recent years in both industry as well
as academia. This is mainly attributed to the unprecedented opportunities they offer. However, WSNs also face
significant design challenges, including their limited computing abilities and their dependence on finite battery
energy. A major obstacle to the ubiquitous deployment of WSNs is the absence of reliable and easy-to-
implement communication stacks. The main design criteria are thus to lower algorithmic complexity to facilitate
low-power solutions that can be embedded into low-cost microprocessors, and to extend the lifetime of the
network without jeopardizing reliable and efficient communications from sensor nodes to other nodes as well as
to data sinks. Such stringent design requirements can be met by a plethora of approaches, e.g., using cross-layer
design paradigms, distributed signal processing algorithms, energy-efficient medium access control, fault-
tolerant routing protocols, self-organizing and self-healing sensor network mechanisms and reliable data
aggregation algorithms, among others. Viable solutions will impact both commercial activities as well as
standardization approaches, including IEEE 802.15.4, IETF ROLL, Wireless HART and WOSA. In light of the
above, the main purpose of this special issue is twofold:
 to promote novel approaches in analyzing, designing and optimizing large-scale energy and complexity
constrained WSNs, and
 to expose novel, readily deployable protocol solutions that are of low complexity and hence facilitate
very cheap network deployment and maintenance, with the ultimate goal of obtaining a useful and
practically viable wireless sensor networking solution.

Topics of Interest:
The topics relevant to this special issue include but are not limited to:
 performance bounds (link and network capacity, with and without imperfections, etc.)
 data centric approaches (data fusion, aggregation, source coding, signal processing, etc.)
 protocol centric approaches (novel PHY, MAC and networking paradigms, etc.)
 cross-layer and cross-functionality designs (joint source/channel coding, etc.)
 cooperative and distributed algorithms (cooperative PHY, distributed signal processing, etc.)
 key functionalities (security, localization, self-*, synch., abstraction, ease of programming, etc.)
 interdisciplinary approaches (principles borrowed from physics, etc.)
Papers must be tailored to the problems of WSNs and explicitly consider complexity and energy constraints.
